POWDER-BOX.

SPECIFICATION forming part of Letters Patent No. 621,780, dated March28, 1899.

Application filed September 22, 1897. Serial No. 662,531. (No model.)

of New York, have invented certainnew and useful Improvements inPowder-Boxes, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improved powder-boxof that class in which the powder is discharged from the box as desiredthrough one or more openings in a discharge-tube, the especial object ofthe I 5 invention being to provide a simple, cheap, and durableconstruction for this purpose in which the box shall be convenient ofuse and the escape of powderprevented, except as desired, through theopening in the dischargezo tube.

For a full understanding of the invention a detailed description of aconstruction embodying all the features of the invention in theirpreferred form will now be given in con- 2 5 nection with theaccompanying drawings, forming a part of this specification, and thefeatures forming the invention will then be. specifically pointed out inthe claims.

In the drawings, Figure 1 is a perspective 0 view showing the positionof the box in opening the same. Fig. 2 is a side view of the box open.Fig. 3 is a similar view of the box closed. Fig. 4 is a central verticalsection of the box, taken through the discharge-open- 5 ing and showingthe box open, as in Fig. 2.

Fig. 5 is a perspective view of the dischargetube asit appears afterexpansion of the lower end. Fig. 6 is a perspective view of thespring-sleeve.

Referring to said drawings, A is the box, which is shown as of aconstruction suitable for tooth-powder and is preferably cylindrical, asshown, but which may be of any other suitable form, and B is the coverclosing the top of the box and secured thereto in any suitable manner.In the top of the cover B is inserted the cylindrical discharge-tube O,which is open to the box at its inner end and closed at its outer endand which is provided with one or more discharge-openings 1 on the side,thus forming a side discharge-tube. The discharge-opening 1 is shown asconsisting of a single opening and oblong, as is preferable in the caseof boxes used for toothpowder; but it will be understood that the numberof discharge-openings may be increased as desired, in accordance withthe use to which the box is to be put. If the box is to be used for faceor similar powders where a sprinkling action is desired, the discharge6o portion of the tube 0 may be perforatedwith a large number of smalldischarge-openings.

The discharge opening or openings 1 are opened and closed by therotation upon the discharge-tube C of a spring-sleeve D, inclosing thetube and provided with the opening 2, which is brought into registrywith the discharge-opening 1 in thedischarge-tube 0 when powder is to bedischarged. This sprin gsleeve D is preferably formed by rolling thepiece of metal forming the sleeve upon a mandrel of smaller size thanthe discharge-tube O and then springing the sleeve into position uponthe tube 0. The space between the edges of the spring-sleeve preferablyform the discharge-opening 2 through the sleeve, as shown, although aseparate opening may be provided for this purpose, and the tube 0 ispreferably of the form shown, provided with a small knurl 3 below thesleeve D and the cap-knurl 4 above the sleeve D. With this preferredconstruction the spring-sleeve is held in position longitudinally of thedischarge-tube by the two knurls 3 4 and is applied to thedischarge-tube by springing it over the small knurl 3 and pushing itinto place over'said knurl and longitudinally of the discharge-tube. Thespring-sleeve should fit quite tightly upon the discharge-tube toprevent leakage of the fine powder between 0 the tube and sleeve and toprevent the opening of the box by accidental rotation of the sleeve uponthe tube.

While the spring -sleeve D may be used with a smooth surface, Ipreferably roughen 9 5 the sleeve or provide it with a series ofprojections 5, as shown, which may be formed by striking up the metal,by which projections the sleeve may more readily be held by thefingersin opening and closing the box. The spring-sleeve may be free torotate entirely about the discharge-tube; but I preferably employ a stop6 on the tube, engaging the sleeve to limit its movement beyond acertain point, while at the same time permitting the sleeve to rotatesufficiently to secure the full opening and efficient closing of thedischarge-openin g 1. This stop is preferably arranged as shown, so asto stop the sleeve in proper position both in opening and closing thebox.

The discharge-tube C may be secured to the cover B in any suitablemanner but the construction shown is simple, cheap, and efficient and initself forms a specific feature of the invention. It is desirable thatthe knurl 3 below the spring-sleeve D and over which the latter issprung should project but slightly, so as to secure its properspringpressure about the discharge-tube, and with the small knurldesired the inner end of the discharge-tube cannot well be rolled uponthe inner surface of the cover, so as to secure the firm-holding andpowder-tight joint desired. I avoid this difficulty and secure anefficient and durable construction by spinning the opening in the coverinward or eyeleting it to form the flange 7, projecting inwardly of thebox and longitudinally of the dischargetube, through which the inner endof the discharge-tube Ois passed, and then spreading or expanding theinner end of the dischargetube and flange 7 slightly, as shown, whichmay readily be done. I have found that a strong powder-tight joint maythus be formed with the knurl 3 of the small projection desired.

My invention provides a very cheap and durable construction ofpowder-box by which the escape of powder is efficiently prevented exceptthrough the discharge-opening, as desired, and the box is veryconvenient in use. A very desirable feature is that the dischargeopening1 may readily and with certainty be brought on the upper side of the boxin opening, so that the accidental dropping of the powder from thedischarge-tube in opening is avoided. This result is secured in the mostconvenient and natural manner of handling the box in opening, whichconsists in holding the spring-sleeve D by the fingers of the left handwith the opening 2 upward and the box in a horizontal position, rotatingthe box by the right hand until the opening 1 is brought opposite theopening 2, as shown in Fig. 1, the powder then being discharged throughthe openings 1 2 by moving the box into the desired position by theright hand.

It will be understood that my invention is not to be limited to theexact construction shown, but that many modifications may be madetherein without departing from the invention.
